RUBBER BOOT OR SHOE.

SPECIFICATION forming part of Letters Patent No. 777,683, dated December 20, 1904.

Application filed December 21,1903. Serial No. 185,987.

To (ZZZ whom, it 711/007 concern.-

Be it known that l, l'lERBERT C. Mason, a citizen of the United States, residing at Providence, Rhode Island, have invented certain new and useful Improvements in Rubber Boots or Shoes, of which the following is a specification.

My invention belongs to that class of rubber boots and shoes which have an outer sole of leather. Heretofore leather soles have been attached to rubber boots and shoes by stitching directly through the sole; but this renders the boot or shoe liable to leak. it has also been proposed to apply such outer leather soles to a rubber sole, which rubber sole is directly attached to a middle sole and extends laterally to form a welt to which the leather was stitched. This plan, while it avoids the injurious perforation of the sole and consequent liability to leak, did not afford a sufliciently firm connection of the leather sole to the boot or shoe, Therefore for the purpose of forming a secure union of the leather sole to the rubber boot or shoe and at the same time to avoid stitching through the sole into the boot I have applied to the middle sole a rubber sole which extends also upwardly and laps upon the upper, to both of which it firmly adheres, and to this overlapping sole I apply,

a rubber sole which extends laterally to form the welt for the leather sole. It is to be noted alsothat this overlappingsolc cxtendsthroughout the entire sole of the boot or shoe, and the Welt-sole extends in like manner throughout the length of the boot or shoe.

I have illustrated my invention in the accompanying drawings, in which- Figure 1 represents part of a boot containing my invention in side elevation. Fig. 2 shows a central longitudinal section of the same, and Fig. 3 is a cross-section on lines a; w of Fig. 1.

1n the drawings the upper and vamp are of the ordinary construction, as is also the inner sole. The upper 1 is lapped underneath, as usual, and its edge abuts against the middle sole 2. Over this or any equivalent construction I lay the overlapping sole 3, the edge of which on both sides (and from end to end, preferably) extends upon the margin of the upper to any desired extent, as shown in the drawings, to the point a. This sole is ofrubber, although it may have interposed or incorporated fabric. The overlap on the upper forms when the parts are united (in the usual Way) a very strong union, and over this sole the rubber sole 5 is placed. This sole is extended laterally throughout the boot or shoe to form a welt for the stitching, which holds the leather sole thereto. It is made of rubber, preferably with incorporated fabric, and its rubber surface adheres to and is incorporated lirmly with the under rubber surface of the overlap-sole below the turned-up margin. This forms a secure and strong connection. The leather sole 6 is preferably cemented to the welt-sole and at its margin is stitched to the welt by stitches 7 passing therethrough. The overlap-sole 3 is thus provided with a welt extension 8, which is coextensive with the welt extension of the welt-sole, and these welt extensions and the leather sole are united by the stitches above described and by ccmenting them together. The holes for the stitching are thus placed all outside of the shoe, preventing any possibility of leaking through said holes, and yet the connection formed by the cemented union of the over lapping sole 3 and the integral welt-sole5 has all the strength of continuous rubber. I am aware that it has been suggested heretofore to unite a welt-strip upon one edge upon the upper and the other, turned outward, upon a welt; but this I have found impracticable for reasons connected with the manufacture, and I do not in my claims intend to include such an outwardly-turned strip.

1 claim as my invention 1. In combination in a rubber boot or shoe, the two soles 3 and 5 of rubber united or cemented together, the said sole 3 being imperforate and overlapping on the outer side of the upper and the sole 5 providing a laterallyextending welt, and a leather sole connected with said welt by stitching passing therewith the said rubber welt, substantially as clethrough. scribed. IO

2. In combination, in a rubber boot or shoe, In testimony whereof I aflix my signature in the upper, a rubber sole 3 extending across presence of two witnesses.

5 below the upper and up on the outside of the HERBERT C. MASON margin of the upper and having associated Witnesses: therewith a laterally-extending welt of rub- G. W. DAILEY, J r.,
